Available in PDF, EPUB and Kindle. Book excerpt: The spin structure function g2(x, Q2) and the virtual photon asymmetry A2(x, Q2) were measured for the proton using deep inelastic scattering. The experiment was conducted at the Stanford Linear Accelerator Center (SLAC), where longitudinally polarized electrons at 29.1 and 32.3 GeV were scattered from a transversely polarized NH3 target. Large data sets were accumulated using three independent spectrometers covering a kinematic range 0.02 (less-than or equal to) x (less-than or equal to) 0.8 and 1 (less-than or equal to) Q2 (less-than or equal to) 20 (GeV/c)2. This new data is the first data precise enough to distinguish between current models for the proton. The structure function g2{sup p} was found to be reasonably consistent with the twist-2 Wandzura-Wilczek calculation. The Q2 dependence of g2 approximately follows the Q2 dependence of g2{sup WW}, although the data are not precise enough to rule out no Q2 dependence. The absolute value for A2{sup p} was found to be significantly smaller than the Soffer limit over the measured range. The virtual photon asymmetry A2 was also found to be inconsistent with zero over much of the measured range.

Download or read book Low Q2 Measurement of G2p and the LT Spin Polarizability written by and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: JLab has been at the forefront of a program to measure the nucleon spin-dependent structure functions over a wide kinematic range, and data of unprecedented quality has been extracted in all three experimental halls. Moments of these quantities have proven to be powerful tools to test QCD sum rules and provide benchmark tests of Lattice QCD and Chiral Perturbation Theory. Precision measurements of $g_{1,2}^n$ and $g_1^p$ have been performed as part of the highly successful `extended GDH program', but data on the $g_2^p$ structure function remain scarce. We discuss here JLab experiment E08-027, which will measure quantity $g_2^p$ in the resonance region at low $Q^2$. These data will be used to test the Burkhardt-Cottingham sum rule and to extract the higher moments $\delta_{LT}^p(Q^2)$ and $\overline{d}_2^p(Q^2)$. Data in the $Q^2$ range $0.02

This book was released on 2002 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have measured the spin structure functions g2{sup p} and g2{sup d} and the virtual photon asymmetries A2{sup p} and A2{sup d} over the kinematic range 0.02 (less-than or equal to) x (less-than or equal to) 0.8 and 0.7 (less-than or equal to) Q2 (less-than or equal to) 20 GeV2 by scattering 29.1 and 32.3 GeV longitudinally polarized electrons from transversely polarized NH3 and 6LiD targets. Our measured g2 approximately follows the twist-2 Wandzura-Wilczek calculation. The twist-3 reduced matrix elements d2{sup p} and d2(superscript n) are less than two standard deviations from zero. The data are inconsistent with the Burkhardt-Cottingham sum rule if there is no pathological behavior as x --> 0. The Efremov-Leader-Teryaev integral is consistent with zero within our measured kinematic range. The absolute value of A2 is significantly smaller than the A2

Available in PDF, EPUB and Kindle. Book excerpt: Jefferson Lab is currently one of the facilities leading the investigation of the spin structure of the nucleon. Over the past 15 years, several high precision measurements have been completed, extending our knowledge of the polarized structure functions g1 and g2 down to Q2 = 0.02 GeV2. In particular, the low-Q2 range (≤ 0.1 GeV2) from these data allows us to make a benchmark-check of Chiral Perturbation theory ([chi]PT). Previous results for the moments of the spin structure functions in this region have shown mixed agreement. For [Gamma]1, the first moment of g1, we find good consistency between data and theory. However, we have seen a surprisingly large discrepancy with [chi]PT calculations for the [delta]{sub LT} spin polarizability on the neutron, which is significantly less sensitive to the [Delta]-resonance contribution. These proceedings will discuss the recent experimental effort at low Q2 from Jefferson Lab, including a discussion of preliminary results on the neutron. The new results on the neutron still show a sizeable discrepancy between data and theory. However, new calculations show improved agreement with data for some observables. In addition, new proton data for g2 is also expected to help resolve the disagreement for [delta]{sub LT}.
